I run the testsuites with "--target_board=unix'{-m32,-m64}'", making the
other tests run with both -m32 and -m64.  I see abi_check being built
both ways and two summaries, but both summaries are identical.

Configuring GCC on powerpc64-linux to generate 32-bit objects by default
is done for the compilers in SLES9 and RHEL4, so it's not unusual.  See
config/rs6000/t-linux64 for the usual multilib directories.
